IVF BREAKTHROUGH USING 3‑PERSON DNA LEADS TO 8 BABIES BORN FREE OF GENETIC DISEASE

Summary from the TLDR newsletter

Eight babies were born healthy thanks to a groundbreaking new DNA-enhanced IVF technique aimed at preventing children from inheriting severe, incurable mitochondrial diseases from their mothers. The babies were born to seven mothers at high risk of passing on severe mitochondrial DNA diseases. The novel IVF method utilizes DNA from the mother's egg, the father's sperm, and healthy mitochondrial DNA from a donor. Children conceived via this technique inherit the vast majority of their DNA from their biological parents, but they also receive a minute amount of healthy mitochondrial DNA from a third person, a genetic alteration that will be passed down to future generations.
